Greg, We have a similar issue with SMTPD. Our external mail will completely drop off until I restart the SMTPD service at which point it immediately picks up again. Our internal mail however is fine. I have not been able to work it out even with several calls to Ipswitch and our proxy server people.

I restarted all of the services, the queue started going down, and the machine was back to normal operation (30 in the queue) in 15 minutes. This seems to be relatively common thing for us, check the queue, if it's over a few hundred, restart the services, and it's back to normal. Anyone got any ideas? I downloaded the log and from 11:53 till 14:32 my mail server I noticed there is not a single rdeliver, but there are a whole lot of MX connect fails. Here are two examples: 02:26 11:54 SMTP-(05F4B480) processing E:\IMail\spool\Q40cc09cb009a266a.SMD 02:26 11:54 SMTP-(05F4B480) [x] looking up qwest.net in HOSTS and MX 02:26 11:54 SMTP-(05F4B480) Info - Found qwest.net in DNS Cache 02:26 11:54 SMTP-(05F4B480) Trying qwest.net (0) 02:26 11:54 SMTP-(05F4B480) [x] Connecting socket to service <SMTP> on host <qwest.net> using protocol <tcp> 02:26 11:54 SMTP-(05F4B480) [x] using source IP for mailserver.webo1.com [66.7.175.35] 02:26 11:54 SMTP-(05F4B480) Info - Found qwest.net in DNS Cache 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.1" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.2" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.3" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.4" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.5" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.6" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.7" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.8" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.9" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.10" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.17" 02:26 11:54 SMTP-(05F4B480) MX connect fail "63.226.138.18" 02:26 11:54 SMTP-(05F4B480) requeuing E:\IMail\spool\Q40cc09cb009a266a.SMD R0 T1 02:26 11:54 SMTP-(05F4B480) finished E:\IMail\spool\Q40cc09cb009a266a.SMD status=3 02:26 14:31 SMTP-(05800000) processing E:\IMail\spool\Q04505a92f501.FWD 02:26 14:31 SMTP-(05800000) [x] looking up aol.com in HOSTS and MX 02:26 14:31 SMTP-(05800000) Info - Adding aol.com to DNS cache - TTL = 185 02:26 14:31 SMTP-(05800000) Trying aol.com (0) 02:26 14:31 SMTP-(05800000) [x] Connecting socket to service <SMTP> on host <aol.com> using protocol <tcp> 02:26 14:31 SMTP-(05800000) [x] using source IP for mailserver.webo1.com [66.7.175.35] 02:26 14:31 SMTP-(05800000) Info - Found aol.com in DNS Cache 02:26 14:31 SMTP-(05800000) MX connect fail "64.12.138.57" 02:26 14:31 SMTP-(05800000) MX connect fail "205.188.159.217" 02:26 14:31 SMTP-(05800000) MX connect fail "205.188.159.249" 02:26 14:31 SMTP-(05800000) MX connect fail "64.12.138.152" 02:26 14:31 SMTP-(05800000) requeuing E:\IMail\spool\Q04505a92f501.FWD R0 T5 Thanks ---greg To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
